First you need to obtain TagLib for OS X. The easiest way is through Fink. After installing fink you're going to have to download the Audio::TagLib tarball yourself and patch it. Follow these steps:
- Download the tarball.
- Open up a terminal and go to where it was download, and untar the file.
- Download the patch into the source directory.
- Run:
patch -p1 < osx-patch.diff perl Makefile.PLmake && make install
Now you should have a working Audio::TagLib install.
